ABSTRACT:
In a digital computer system running a windows operating system and a video editor where the video data is stored in the memory and clips of the video data consisting of sequences of video frames are represented by blocks in a workspace on the video display. A video cursor is provided to scroll through the frames. The disclosure describes a convenient method of allowing the user to control the scale of the horizontal axis and thus the number of video frames that may be symbolically viewed on the workspace window without panning. The method includes the following steps: First, determining if the video cursor is being intentionally moved vertically by a user. Next, determine the vertical distance that the video cursor is moved from a reference point. Finally, adjust the number of video frames that may be represented on the workspace in relationship to the vertical movement of the video cursor.
